The gas phase oxidation of o-xylene to phthalic anhydride at low oxygen concentration was studied.

近年来，国外对邻二甲苯氧化制苯醉的高负荷催化剂进行了大量的研究工作，其中V-Ti系催化剂得到广泛的应用

Factors influencing TiO_2-PILC photocatalystic properties were discussed, including the ratio of CH3COOH and Ti, the temperature and aging time of pillaring agents, pH value of reaction solution, the temperature of calcined, etc.

以钛酸四丁酯为前驱物，冰醋酸为鳌合剂，重点考察了[CH3COOH]/比、柱化剂制备温度和陈化时间、催化剂煅烧温度等对TiO_2柱撑蒙脱土结构的影响。

The results indicate that the pillaring process and crystal growing of anatase can be more easily realized by increasing the acid-base ratio of pillaring agents, raising the pillaring temperature and adding proper quantities of alkali. The calcination of Ti-pillared precursor brings the growth of TiO2 grain, at the same time the layer distance is declined. In order to obtain ideal products, the right pillaring conditions are: the acid-base ratio of pillaring agents of 13, pillaring temperature of 65 ℃ and the volume of alkali (2 mol/L) in pillaring liquid of 6 mL.

结果表明：在一定范围内增大柱撑剂酸碱比、提高柱撑温度以及加入适量碱，有利于插层复合反应的进行和锐钛晶型的生长；柱撑前驱物焙烧后TiO2晶粒长大，同时焙烧引起的脱水导致膨润土层间距的下降；为获得较理想的产物，合适的柱化条件为：柱撑剂酸碱比 n n (HNO3)为13、柱撑温度65 ℃和柱撑液加碱量为(2 mol/L NaOH) 6 mL。

The Ti-enriched slag up to 90--98% TiO_2 may be producedby prereduction of the LUDA ilmenite with plasma smelting.

结果表明，预还原钛铁矿经等离于熔练，可得到含二氧化钛90—98％的富钛渣。

Mo Ti championed the cause of the peasants and puritanically stressed the virtues of hard work.

墨子支持农民的事业，极端拘谨地强调勤劳的美德。

I'll take the full quan ti ty you offer.

你提供的数量我全部都要。

I'll take the full quan ti ty you

Supercontinuum with an ultra-broad bandwidth of 380 nm to 1750 nm was generated by injecting 250 kHz, 200 fs optical pulses produced from a regeneratively amplified Ti:sapphire laser into a 2.5 m-long polarization-maintaining photonic crystal fiber.

在800 mW的输入功率下得到了超连续谱的输出功率为60 mW；采用钛宝石放大器泵浦保偏PCF得到了谱宽为380 nm-1750 nm的超连续谱，带宽超过了两个倍频程。

It is expressed as a function of the temperature expansion coefficients of the crystal lattice, their remanent polarization and other parameters.

用&纯&PbZr_xTi_(1-xO_3的实验数据代入表达式计算，得到准同型相界附近组成的T_对Zr/Ti的关系曲线，与实验结果较好地符合。

The behaviour of oxygen in the reoxidation process was investigated by an oxygen coulometry.

结果表明；氧流量计在升温阶段检测到三个不同行为的吸氧峰，峰Ⅰ（起始温度-250℃）为氧空位的填充过程；峰Ⅱ（起始温度-800℃）和峰Ⅲ（起始温度-1250℃）为还原相的氧化过程，具体来说，峰Ⅱ是通过晶界扩散提供氧使靠近晶界附近的区域被氧化；而峰Ⅲ是由晶格扩散过程控制，氧化过程从晶界逐渐向晶粒内部区域扩展，并伴随着富Ti的Ba6Ti17O40相的沉淀。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
